Quantum Physics tells us that the universe is just basically program. Think of Second Life. We are the programmers and we can choose any program we wish to experience. Every time we make a choice we split the universe and create a new parallel one. We do this eternally so the one mind is fractured into bazillions of other minds that are all creating their own realities at once. The higher dimensional existences like Pleiades and Sirius are programs just like we are. We all have multiple existences beyond this one. Try to wrap your head around that for a minute. We are not just Earthlings. We are little minds creating just one little reality in the sea of MIND.
In fact we are physically trapped (sort of) in a program that was designed by other yous. We chose to experience this world and we create other worlds just like it just by participating in this one. Right now there are bazillions of other yous that turned right instead of left and became that instead of this. So worrying about what will happen to you or the earth is pointless.
